Antibodies against PLA2R are highly specific serological markers of IMN
anti-PLA2R levels in IMN are associated with disease activity as measured by proteinuria and other biomarkers;
positive PLA2R Ab status is linearly associated with proteinuria over time;
the probability of halving proteinuria is significantly increased (6.5 times) after negativization of anti-PLA2R Abs;
in IMN patients anti-PLA2R Ab serial measurements could help optimal timing and duration of the immunosuppressive therapy.
